Title:
PRODUCTION OF POLYMER OR COPOLYMER CONTAINING UNSATURATED GROUP
Document Type and Number:
Japanese Patent JPS62124102
Kind Code:
A
Abstract:

PURPOSE: To easily produce the titled (co)polymer, by carrying out radical (co)polymerization of a conjugated unsaturated monomer using a polymerization initiator consisting of a diperoxy dicarbonate having a specific non-conjugated unsaturated bond.

CONSTITUTION: A conjugated unsaturated monomer is polymerized by radical polymerization usually at 30W90°C using a polymerization initiator consisting of a diperoxy dicarbonate of formula I (R1 is H or CH3; R2, R3 and R4 are H, CH3 or C2H5; n is 0W3) having non-conjugated unsaturated bond. The amount of the polymerization initiator of formula I is preferably 0.05W20wt%, especially 0.5W8wt% based on the unsaturated monomer.

EFFECT: A wide variety of conjugated unaturated monomers can be used as the raw material.

USE: Useful as a crosslinking polymeric material or crosslinking additive, etc.
